1,2,4,101,202,404
Greatest Common Factor
We found the factors 18,681,404 . The biggest common factor number is the GCF number.
So the greatest common factor 18,681,404 is 1.
Lets's calculate LCM of 389,719,449
Given numbers has no common factors except 1. So, there LCM is their product i.e 125581259
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/125581259
Therefore, the GCF of Fractions 18/389,681/719,404/449 is 1/125581259
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 389,719,449 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(389,719,449) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(389,719,449) x common factors =1 x 1 = 1
LCM(389,719,449) = ( 389 × 719 × 449 ) / 1
LCM(389,719,449) = 125581259 / 1
LCM(389,719,449) = 125581259
